After debating the issue among ourselves for some time, husband and I finally applied for, paid for and received our passport cards, which we are told to keep jacketed in our wallets to prevent unauthorized access. It was a hassle for us but we did it. Since then we have gone to Windsor a couple of times and it has been no problem. The border crossings were smooth and there wasn't a long wait at the bridge. I have an Indian card which I can use at the International Bridge in the Soo, but I have been discouraged here by the pugnacity and ignorance of certain border agents. My granddaughter has no other ID and had no trouble in the Soo, crossing with her Indian ID.
